Answer:
x = - 3
Step-by-step explanation:
Given
[tex]\frac{2}{3}[/tex] x + 5 = 3 ( subtract 5 from both sides )
[tex]\frac{2}{3}[/tex] x = - 2 ( multiply both sides by 3 to clear the fraction )
2x = - 6 ( divide both sides by 2 )
x = - 3

I'm having a hard time understanding square roots, especially Non-Perfect ones. I'm stuck on a question where we have to find the two integers closet to the number in the middle (68) and I can't seem to understand it at all.
8 and 9 because you would need to multiply 2 of the same number like 1×1 2×2 3×3 4×4 5×5 abd etc. 8×8=64 and 9×9=81 so 68 would be in the middle of those two

There are 257 people at a dance performance. Orchestra seats cost $12 and balcony seats cost $8. The total receipts were $2,716. Find the number of orchestra seats and the number of balcony seats sold for the performance.
x = # of balcony seats
y = # of orchestra seats
We have to create a system of equations to solve this problem
x + y = 256
$8x + $12y = $2,716
We will solve this system of equations by elimination.
Multiply the first equation by -8
-8x - 8y = -2048
8x + 12y = 2716
Let's add the equations together
0 + 4y = 668
Simplify the left side
4y = 668
Divide both sides by 4
y = 167
We can subtract 167 from 257 to get the number of balcony seats.
257 - 167 = 90 balcony seats
There are 167 orchestra seats and 90 balcony seats
The number of orchestra seats and the number of balcony seats sold for the performance will be 165 and 92.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
There are 257 people at a dance performance. Orchestra seats cost $12 and balcony seats cost $8. The total receipts were $2,716.
Let x be the number of Orchestra seats and y be the number of balcony seats. Then the equation will be
x + y = 257 ...1
12x + 8y = 2716 ....2
From equations 1 and 2, then we have
12x + 8(257 - x) = 2716
4x = 660
x = 165
Then the value of the variable y will be
165 + y = 257
y = 92
Thus, the number of orchestra seats and the number of balcony seats sold for the performance will be 165 and 92.
